If you are positioned as a small department leader, you should make it exquisite and not greasy. Lunch is a simple business meal. Just look at how those coffee shops and tea restaurants do it. The food is just a little. You can send someone to learn how to make juice, milk tea and coffee. A simple meal with a drink is low in cost but high in grade. Little lark loves this mouth. You can also send food to their office and issue order cards. Those who work overtime are your guests. If this thing is done well, selling coffee and juice will be a lot of income outside the meal (of course, the quality of your raw materials is better, don't mix boiled water with essence and pigment like 2 yuan milk tea kiosk). Dinner should be the same as fast food, mainly home-cooked food, pay attention to the plate. It's better to have some beautifully photographed specialty dishes and X-display stands at the door. But to be honest, I think this road may be a little narrow, unless the factory is really big and there are many small white-collar workers patronizing it.
Besides, since you drive there, there must be someone in the factory. Let someone help you send the reservation card in and get some small heads to get together occasionally. You can receive these. There are many ways to extend the service to dual employees in factories, such as providing them with family meals at noon, so that they don't have to worry about the lunch of the elderly and children. The key is that you can analyze what kind of catering service they need by positioning yourself and focusing on yourself.
Of course, all catering is based on cleanliness to ensure quality. If it tastes bad, at least you shouldn't dislike it. If you can't, close the door as soon as possible.
